IGNITER NEEDED FOR OLD AMERICAN STANDARD BOILER
Hoping someone can point me in the right direction. I am trying to locate a REPLACEMENT FLAME/SENSOR/IGNITER for an American Standard Boiler
American Standard got out of the boiler business and sold to Burnham a long time ago and I've had difficulty finding someone that may have parts, but I'm hoping someone may have worked on similar systems.
AMERICAN STANDARD BOILER
MODEL: G 40
8SERIAL: 48 J3
I won't be doing the installation. I'm just trying to help the contractor locate the part so they can complete the install and get it up and running.
Here are the pictures I have x 3:
I appreciate any information you can provide.

Can you take a picture of the pilot assembly mounted to the burner and a couple more pictures of the controls inside of the boiler from a little further back? Where do the copper tubes from the thermocouples connect to?
This looks like it is just a standard standing pilot boiler with 2 pilots and either switches or valves controlled by the thermocouples. Someone qualified to work on this should have no problem buying the correct thermocouples if that is the case.

Also a good picture of the lighting instruction plate, above the burners.
Looks like the first and last burners are removed and the jets capped….hopefully.

What's this?
Manual spark, or auto spark?

I think it is a standing pilot with a Baso switch hiding behind the gas pipe, inside the boiler
If the repairman has never seen one, it would be a challenge. Actually simple if one follows the gas train/controls.

A blurry picture of something?

After you make that expensive repair and you still have the same problem, What will you check next?

Your boiler is old enough to be in the "time to replace it" category. You may also be in the "time to update the control system" category. Depends on your economic situation.
As @JUGHNE mentioned, if your contractor is unfamiliar, it can be difficult. Your picture does not have all the information needed. you can order parts that replace the existing parts based on the part numbers of the parts. you probably won't find the parts list based on the manufacturer model and serial number. that heater is too old for that.
What is the problem you are experiencing? You have no heat because the pilot will not stay lit? there is no gas flowing to the pilot? The pilot stays lit but the main burner will not light when there is a call for heat from the thermostat?
More information may give us a clue about this, and what parts to look for at the supplyhouse.com website.

This is a common safety device for that era heating system
Then there is this part that connects to that switch

then there is this gas valve that you may need. or one like it
If you end up needing more than that, then it is time to "Modernize" the control system, or replace the boiler.
Remember the prices on the Supplyhouse.com website are wholesale prices. Any reputable contractor would be justified to add a markup to those costs to a retail customer making those parts more expensive, then adding the labor to replace those parts can get expensive.
Also, what if those parts do not solve the problem? who is going to pay for the time to install them just to find out that it still does not work? You need an experienced oldtimer to find out if you only need the less that $10.00 part or the over $400.00 part and give you the price up front so you can decide if replacing is a better option than repairing.

Have your tech take out the part he needs to replace and take it to a real supply house and they can match it up. That is if he knows what is wrong with it. The part you need is probably made by one of the control companies like Honeywell or Robert Shaw.

if they can't find a thermocouple in a catalog, what are the chances they can properly test one?

My point is looking for a part for an old boiler it is almost pointless to follow the boiler model and serial #. The manufacturer if they still exist (and this one does not) the thermocouples, gas valves igniters were not made by American Standard. They were made by Basso, Honeywell, Robert Shaw, Johnson Controls etc.

Thanks everyone for the advice. I am going to relay this information to the tech and try to get some additional pictures.
